The overall proposed schedule, treatment unit completion and basis for implementation will result in potential violations of water quality standards in the Gallatin River basin. The gap between treatment upgrades and the time allowed for river discharge or land application promotes extended periods of water, groundwater and soil quality violations.
This is not true. The reviewer somehow misunderstood the timeline for MBR implementation (first project) and the results of the preliminary permitting evaluation, both of which reflect the District’s desire to achieve full compliance with water quality standards in the Gallatin River, groundwater and soil quality. The result of the MBR upgrade will be a Class A-1 effluent, which is the highest quality effluent considered in DEQ’s regulations.
